orthe like, and'particularlyhub'retaining or .other nuts, or'rotary members access to whiehis more or .'less limited or restricted.

It is an object 'of the invention to provide a tool or Vequipment .for removing hub retaining nutsor the'like which tool or equipment is constructed so that it can be easily applied in a manner that a nut can bepositively gripped and subsequently removed.

n fAnother object of the invention-is to provide a, itool or equipment for .removing hub retaining nts or'the'like'in eonstricted areas which equipment or tool is o'f simple and inexpensive con-l struction as well as one havin'gapos/itive gripping action when applied and which .cani be operated with `minimum elort to accomplish .a desired result. "'Other objects .and .advantages of the vinvention will become apparent 'from'theifollowing 'description'taken in conjunctionwithlthe. accompanying drawings, wherein:

Briefly 1:stated the inventionr Jcomprises -a pair olfwrench strips with meansfforholdingwand rrrving them toward-and irom'each other "for gripping opposite sidesof anut'aswell as forrotating the mechanism to remove `the nut after the'pdevice'has been applied andY the nut hasbeen gripped.

With contini-led :reierenceztoithe drawings, a

body ,such as, for exampleahub l may,.have an :opening Il and a slightly'eiilarged recess? l2.`

A-.sleeve I3"'hav'ing an externally .threadedportion Il' is adapted to Yreceive a nut"'|'5 of polygonal form, as disclosed in Fig. 1, and later to be described, Within said hub. A tapered roller bearing 50 is disposed within the opening I l and comprises inner and outer races 5I and 52. The outer race 52 is retained in a predetermined position within the opening I I, by means of a shoulder 53 which may be annular and the inner race 5I is brought into engagement with the roller v l6-is Vconcentrieally ymounted. Concentricityis maintained by lmeans of a *collar or bushing 11i held in place "by 'a set screw IB. llhe sleevev v|"6i` serves as va mounting yTor xthe wrench structure',l or mechanismby-means cit-which Lthe nuts are'j adapted to be removed.

By this construction the jaws 30 and 3l may be readily moved into and released from engagement with a nut such as the nut l5.

After the device is applied in the manner de scribed it can be rotated to remove a nut of the character of the nut l5, and in order to :facili-ltate the rotation of the nut removing structureV .4 ward and from each other and locked in contact with the nut to be removed by said other member, and means whereby said axially disposed tube can be rotated for applying and removing a nut.

2. A device of the character described comprising a support, an adjusting member having a cylindrical bearing portion and right and left hand threaded portions of smaller diameter extending therefrom with a shoulder formed at each end `of said bearing portion, said support having spaced walls provided with openings receiving said bearing portion, the exterior surfaces the outer end of the tube l0 is provided with a polygonal surface such as the nut 31 welded to the end of the tube as shown or if desired, vthis type of polygonal wrench engaging portionY may be provided in any desired?y manner.

The nut l5 disclosed in Fig. 1 is of the hexagonal type but where nuts of other types are employed the invention may be modified accordingly, for example, in Fig. 4 a castellated nut 38 is employed having a series of slots 39 for receptiony of ribs on appropriate wrench or sprocket mechanism by means lo fiwhich the nut may bey removed. Howevenin order to properly engage andV grip this vmodified type of4 nut the wrenchk members" 2'8 and v29 are inappropriate and must be vmodiiied. Accordingly,A wrench members l0 andld'l 4are employed having jaws 42 and `43 which convergeslightly at their extremities to conform to andsnugly engage thefsurfa'ce of the nut.

Further, the end-.portions `offth'e wrench mem--v bers havekey portions. and 45 forreception inthe slots39.A The wrench members each have an'u'pper threaded and a lower unthreaded open` ing Afor reception of the .adjusting and locking bolts A2l land 22 previously 'described in connection with the structure of Fig.' 1. I6 isidentieal Iin bothof these figures.

Itwillbe understood that 'bymeans of the abovey described construction'V the wrench 'equipment canV be, readily appliedand used toremove a `nut in a minimum of time;

Itwui be obvious to those skilled in the art that vvarious changes may bemade in theinven-l tionwithout departing'lfr'om the spirit and scope thereof and thereforev the inventionlis not'limited byV that which is shown in thedrawings and dein the appended claims.'
